The heartbroken mother of a fit and healthy 31-year-old who died suddenly in her sleep has issued an urgent plea to young people.

Sudden Adult Death Syndrome, or Sudden Arrhythmic Death Syndrome (SADS), is an “umbrella term to describe unexpected deaths in young people”, usually under 40, when a post-mortem can find no obvious cause of death, according to the Royal Australian College of General Practitioners (RACGP).

“All you know is it wasn’t drugs, suicide, trauma or heart attack,” Dr Paratz said. “You’re still left wondering what it was.”

Last month, the heartbroken mother of a young Irish advertising executive who died in her sleep urged parents to get their children screened for SADS if there was a family history of cardiac illness.

Catherine Keane, 31, was found dead by her flatmates last year.

In another tragic case, a new bride was found dead by her mother-in-law in a UK tanning salon last month.

New Zealander Piata Tauwhare, 30, is believed to have collapsed shortly after starting an 11-minute tanning session at Lextan in South Wales.

(We already told you this would happen!!!) Cardiology researchers have previously suggested that the complex effects of pandemic lockdowns would probably lead to more deaths from heart disease – a phenomenon dubbed “post-pandemic stress disorder” by psychologists in the UK.
